REACTIONS OF 2-ACYLPYRIDINE 1-OXIDES WITH ACID ANHYDRIDES
Nagano, Hiroyuki,Hamana, Masatomo
, p. 3249 - 3257 (1987)
Treatment of 2-acetyl- and 2-propionyl-pyridine 1-oxides (1a and 1b) with hot acetic, propionic and benzoic anhydrides initially gives the respective enol acylates (A), which further undergo deoxygenative β-acyloxylation to give enediol diacylates (E) and
